Hello,
I'm trying to build kdepim 3.5.13 from SVN under RHEL6 with cmake.
When compiling I get the following error: (under libkdenetwork/gpgmepp)

cd /home/albator/rpmbuild/BUILD/kdepim/build/libkdenetwork/gpgmepp &&

It looks like the parameter -lgpg-error is missing after -lgpgme.
It links correctly if I add it manually.

Thanks
